ing drum, 2 the side flanges7 and 3 the drum shaft. `On the winch `frame is mounted the device for controlling the distribution of the cable. This device comprises an arm 7, the end whereof bears a wedge 9 intended to contact with the `windings of the cable upon the drum. The arm 7 lis pivoted at 1Qv so as toswing in a vertical plane, the pivoting point 10 being` free to rotate in a horizontal plane. To that purpose the pivot 10 ismade in one piece with a sleeve 11 threaded about the vertical shaft` 12,` secured in any suitable way tothe winch frame. On'the shaft 12 is also mounted to freely swing, asecond arm 13 `which reproduces the movements ofthe arm- 7, but those movements that this latter arm forms `in the horizontal plane. The conthe arm and the arm 13 in Fig. 1,` said connection formed by cutaway portions of the 11 and 44, as will hereinafter be fully being.

Y The free end ofthe arm 13 is bent upward and is pivotallyconnected to the underside of the plate 14. This plate issup'- ported by two horizontal' which` the plate 14 is free to reciprocate. the movement thereof takingv placeV in a directionparallel toA the shaft of the drum 1.

provided with aslot 16` (Figs. `2` and 4) transverse tothe 'the direction of which is 18 sliding into the guides 19. The positionv guides 15, between v i only l persovr

direction of the movement I A p1vct17 engages the slot pivot beingsecurely fixedto a plate of these guides xiswat right angles to thev Y guides 15. whereby the `plate18 moves at. right angles to the plate 1 4. The plate 1S` forms apart ofa, prolongated arm 20 the end of which is-connectedjto the free end `of aglever 21 pivoted at` 22,7upon the winch frame.

The lever connectedwith atriangu` Y .larframe `E235which isvalso pivoted about the verticalaxis 22. The free end of the "frame, which end is also the vertex of the provided withbearings support- ,y

triangle, is

pulley 5. This pulley bears said pulleys the cable runs to a second pulley `6, thenceto `the body that the Winch must rise or retain (in the case the winch is intended to be used for aeronautical purposes). The operation of the device is clearly understood by looking at lig. 2. In fact any displacement of the arm 7 is reproduced by tlie arm 13 which in turn produces the reciprocation of the plate 14. This reciprocation of the plate 14 through the pivot y,17 .of the plate 18 engaging the slot 16, produces a reciprocating movement at right-angles of the plate 18. This latter through the arm 2O swings the lever 21 about the axis of pivot 22 and causes an angular movement of the trame 23, to which the lever 21 is secured. Y

yTnasmiich as the cable 4'fpasses over the pulley l5 at the` free end of the frame 23, the cable 4 will of course 'in its running toward the'drum 1 'as it is taken up, be gradually and continuously moved romoone end to the other of the drum, and as this latter rotates, the cable locates itsel'f'in the regularv form of a screw thread.

The winding, operations will be under-v stoodby referenceto Figsy, 6, 7 and 8.

Fig. 5 is a View illustrating the beginning ofthe winding on the drumand the formation of the first layer of cable. Fig. 6 shows the vcompletion of the lirst layer of .cable on the drum and the starting of a second layer. F 7 shows the position assumed by the wedge'9 when the lfirst layer of cable is completed and the wedge con! tacts with the end. flange of thefdruni. Fig. 8 shows the positionassumed by the wedge 9 in grinding: the distributer when starting the formation of a new layer. Y

This operation is in tactrontrolled from the movement of the arm 7, which contacts Vwith its wedge 9 with the threads of thev cable as the same is winding upon the drum i.` The wedge 9 contactingwith the threads I of the cable causesthecontinuous displacement of. the lever 7 `trom one end tothe other of the drum,guntilV one `layer.` vofV Y cable has occupied' tlieentire length ofthe drum (Fig. 7), and thereafter thewedge, and its arm, begin to movevin the reverse direction (Fig. 8),*to return 'to the starting point, andvso on again until'the winch stops'. The arm 7 mayalso oscillate; ina vertical planete accommodatethe increasing diameter of the drum 1, due to the several layers of cable vtaken up vduring the winding operation, and vice versai i Theiseveral parts stated,` have Vtheir size',

to produce a reciprocating movement of the frame 23 Vand of course et the pulley 5 from one lend to the other ofthe drum, and with that. speed necessary to dispose the cable Avinthe desired way, said speed being a funcwhich is threaded the wedge 9 connectingr to the arm 7.

The thrust pulley 6 is journaled on the supporting member 25 which is itsell' pivoted about a horizontal axis upon the winch frame thus being free to swing for following the variable inclination oi the cable 4 when the winch is used for aeronautical purposes. `To that end the support 25 is provided with an arm 26 to the upper end whereof are mounted two grooved pulleys 27 between which the cable runs. Furthermore the arm 26 is pivoted with its lower extremity about the shaft of the pulley G, which disposition permits the arni 2G to swing in a plane at right angles with the plane passingvthrougli the axis of the support 25. The combination of these two movements allows the pulley 27 to follow the cable iii any direction, which is of peculiar advantage in the case of' Winches to be used for aeronautical purposes.

In Fig. 2 the two extreme positions of the parts, are indicated respectively iii full lines and in dotted y lines.

From what'has hereinbeifore been said, and from the drawings it is evident that when the cable is given out from the drum 1 the device has no function, and to prevent the movement of the seif'eral parts, the applil cant has devised suitable means to stop the movement of said parts. This lmay be obtained by taking the wedge 9 out of contact with the cable upon' the drum 1. that eiect the lever 28 is used, pivoted at 29 to the winch frame, (Fig. 1) the extended lowerportion 30 of said lever bearing upon the rear extension 31 of the arm 7.

A coiled spring 32 keeps in engagement the extension 30 with the extension 31 and in the mean time forces the arm 7 and its wedge 9 against the drum 1, to assure the necessary Contact between the wedge 9 and the cable threads. With the operation of the lever 28, that is by pulling it towards the right in Figl, the rear extension 31 of the arm 7,

-is forced down, and the wedge 9 is raised leaving the drum. Therefore, as soon the wedge 9 contacts no more with the cable, the

ing operation. To avoid such difiiculty the connecting point between the lever 21 and "the frame 23 is provided with a coupling de o Y. A r vice which may be'brought into or out of and'theirjmovenient combined in such a way positive engagement by the action of a lexi vble controlling cable 33, acted on by the handle 34 mounted. upon the lever 28, als shown.k The frame'23 will remain free to lswing vabout its pivot 22 and will follow the.,v move' vment of the cable from right to le-t, and vice versa, when the cable is given out from the drum 1.

` 21 is secured.

i low,

lowering of the bar ment with the teeth andthe i The couplingis:shownin section in Fig.` 3.

Referring to this figure, at the pivotal point 22, and into thelower side of the frame 23'is formed a coupling device coinprising two members, one of which` is integral and moves with the lever 2l, `and the other with the frame 23. The coupling member of the frame 23, has two teeth 35 between which may be brought into engagement the transversal locking bar 36. This bar is free to move vertically and is cross mounted into a sleeve 37, to which the lever A coiled spring 38 located under -the bar 36, and contained within the sleeve 37, continually forces the locking bar into engagement with the teeth 35 of that part of the coupling secured to the frame 23.

The lower portion of the pivot 22 is holand is provided with two elongated Slots 39 through which passes a stud 4:0 bearing upon thebar 36. To the studv l0 is secured, as shown, the wire of the controlling device 33. By pulling on the wire the stud 4:() is pulled down, taking with itself the bar 36 against the tension of the spring 38. The

36, `leaves outof engagement the teeth 35, thus separating the two members of the coupling. Therefore the frame 23 is free to swing about its pivot 22. When the end of the frame to which is mounted the pulley 5, is intheright position, with relation to the arm"7,this latter is lowered into contact withthe drum; in the mean time theV handle A34C is released, thus releasingthe pull on the wire. rlhe spring 38 will push the bar 36 again into engageframe 23 is again coupled with the lever 21, and through theparts described, to the arm .7.

For allowing a certain play, between the i :arm t and the arm 13, for accommodating the variationsof position between the "working conditions, `23 and the arm 7 arising 'from'the actual i is pivoted the Aarm which is secured theiarm 13 d eo frame the sleeve 11 to which working conditions, the sleeve ll to which connectedleaving aspace between the 0H- set portions or teeth il of the sleeves 1l and lll respectively. The amount of *play between the two sleevesis regulated means of the screws 42 screw-threaded through the portion 4l, and comingat a suitable distance withthe teeth 43, which distance maybe regulated at will, as it is easily understood.
